Which Antivirus do you recommend for Windows 7? I think I have three main options, but if you think there's something better, please go ahead. a. There's the Kaspersky Internet Security that comes with Parallels 6, I think they offer a complete 1 year membership (included), after the 1 year period, paying will be needed. If I decide to uninstall it after the year, I assume this should be easy to do. b. Then there's AVG, which is probably the best free antivirus. c. And I've been told recently that Microsoft Security Essentials is also another contender. Which antivirus do you guys use and why?
